-- Information about the crash:
- What I was doing when the application crashed:

I was simply opening up Firefox after logging into KDE and nothing more.  I had clicked on Firefox under my Kickoff application launcher favourites menu.  Firefox didn't seem to be doing anything so I clicked firefox again, still nothing.  Then I got the error about Plasma Desktop having crashed and do I want to report it.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
